How is lupus diagnosed?

ANSWER

Lupus is diagnosed when a person has several features of the disease (including symptoms, findings on examination, and blood test abnormalities). The American College of Rheumatology has devised criteria to assist doctors in making the correct diagnosis of lupus. A person should have at least four of the following 11 criteria, either at the same time or one after the other, to be classified as having lupus. These criteria include:

1. Malar rash

2. Discoid rash

3. Photosensitivity

4. Oral ulcers

5. Arthritis

6. Kidney disorder

7. Neurological disorder

8. Inflammation of the lining around the lungs (pleuritis) or of the lining around the heart (pericarditis)

9. Blood disorder

10. Immunologic disorder

11. A positive antinuclear antibody test result from blood work (abnormal bloodwork)
